OMG!!!!111 People like you make me sick. I've a good mind to tell you "your an idiot" or, even better "ur an idiot".
Anyone with half a braincell [myself included] knows that Alessandro Volta conceived the idea of the battery back in the 1800's, John Logie Baird pioneered the concept of electrically projecting imagery on a screen in 1926 and, as long ago as the Paleolithic era, the inhabitants of Lascaux in France were using their fingers to manipulate imagery on their cave walls.
In addition, Xerox PARC were researching a prototype tablet style device, back in the early 1970s. Housed in an aircraft hanger, powered by six commercial diesel generators and cooled by liquid nitrogen, the 'Xerox-Block' was operated with a 3ft wide concrete finger, fired at the screen using a bazooka and could display the number "7" and the letter "G" for up to three seconds, before shutting down to avoid self-combustion.
When are all those Appletard fanbois out there going to face up to this and admit that the iPad is nothing but a huge failure, cobbled together from stolen ideas and marketed at morons, baffled by anything shiny.
I'd like to say more, but I'm worried that all this froth might damage my keyboard. Beside which, I've got some 'real' computing to do. I'm just going to change my terminal prompt to a different colour and can't quite decide between entering:
"PS1='\[\e[0;32m\]\u\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[1;32m\]\$\[\e[m\] \[\e[1;37m\]'"
"PS1='\[\e[0;31m\]\u\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[0;31m\]\$ \[\e[m\]\[\e[0;32m\]'"
at the command line.
